These both perform conditional subtraction, returning the minuend and zero respectively, if the difference is negative.
AMDGPU has instructions for these. Currently we use target intrinsics for these, but those do not carry the ordering and syncscope. Add these to atomicrmw so we can carry these and benefit from the regular legalization processes. Drop and upgrade llvm.amdgcn.atomic.cond.sub/csub to atomicrmw.
Note that in GFX12 onwards "csub" is renamed to "sub_clamp" - the atomicrmw operation uses the newer name.
